But does it have copilot?
I have my own copilot. It’s called domestic partner.
So you do pair programming or..?
I just uninstalled the UWP Notepad and use the old one. But I guess some people need hobbies.
What’s wrong with having hobbies?
It’s illegal.
Plummers YouTube channel is excellent btw
People who programmed in the 80s and 90s are all pro golfers. Modern coders could learn from them.
Who cares about file size? It would be more impressive to optimize it for better performance / less memory usage
I suspect a 2.5kb application would probably load quickly and use little memory.Edit: I’m an illiterate dumdum. Don’t upvote.
It says this right in the article. Is reading the article too much to ask?
They don’t say the scenario where that’s happening, though. Unless your editor supports large file editing, a mode where it doesn’t load the whole file into memory, unless it has filesize restrictions that make it just fail, if you throw a large enough file at it, it’s invariably going to use a bunch of memory.
On my system, after it (slowly) finishes opening that file,
vim’s using 511MB RSS. I know thatvimhas some sort of large file editing support, though not how to use it.On emacs, large file editing support is from the
vlfpackage.Emacs is using 75.3 MB RSS after opening that.
They do, in the linked GitHub issue:

Apparently, that’s just sitting idle.
By not optimizing for file size with Crinkler, the executable grows by a factor of 4 and RAM usage shrinks by a factor of 300. This build will probably be made available to people who value 500 MB RAM per running instance more than the 9 kiB of disk space saved (I assume that’s anyone wanting to use it in practice).
Yes apparently. Apologies.
Size on disk doesn’t correlate to memory usage or load time. You can get a very small on disk size by compression, or downloading the main executable at runtime.
The premise is probably if you can optimize the code to be small, you are probably also optimizing how it runs too. Rather then just bloat up everything
Once you start optimizing for one aspect, others become less important. In this case, they are doing a few hacks to get to 2.5kb, which do impact runtime performance. A few users report it using 500mb at runtime due to the compression :/
Sure. I wasn’t thinking of something like .kkreiger. I assumed that a small simple text editor would use a similarly small amount of memory. Shocked it ballooned so big. Sorry can’t read the article at the moment.
It does some of the tricks that .kkreiger uses, including compressing the binary.
And at least according to a few reports, it uses 500MB of ram:

Oh my god thanks for these memories
demoscene & 64K intro
The size of the main binary and all the libraries loaded does determine the starting point of the memory usage, but then doing things like loading files are going to also use memory and there are many strategies for optimizing for speed, memory usage, disk size that have tradeoffs between them. Anyway the point is that the size of the program itself isn’t irrelevant even though it isn’t the only factor in memory usage.
Even the linked libraries may not contribute anything, if they are already loaded and shared amongst other processes. There are so many factors and trade offs that you cant really make any assumptions based off just the executable size.
